I have board where I can't connect to the FPGA's JTAG pins. Nevertheless, it would be nice to be able to use the SignalTap II tool to have a look what is going on inside the FPGA - a Cyclone II device.
Is there a way of using SignalTap II through another interface (got some spare pins) than JTAG?

You're going to be out of luck.
The SignalTap II component is highly integrated with Quartus, and its unlikely you can massage the results into anything that would route to anything but the FPGA JTAG pins.
Can you route jumper wires from some I/O pads to the JTAG pins? You could then instantiate a SignalTap II component that does use the JTAG pins, but then use your communications interface to access the JTAG pins.
